Emotions in War: The Emotionality-Rationality Equation in Clausewitz’s Theory of War

Clausewitz introduced an inclusive equation between emotionality and rationality with regards to the debates on the causality and practice of war in modern strategic thought. In Clausewitz’s theory of war, war is a process of governmentality composed by three types of actors: states directing war (leaders and decision-makers), armies executing war (combatants), and people supporting war financially and morally (societies). In this trinitarian scheme, war is a continuous, mutually constitutive interactional process with emotional and rational components both between conflicting parties, and within each side. The aim of this article is to discuss how Clausewitz integrated the emotion-reason equation in his theory of war, to explain through an actor-level analysis how emotions affect, change, and transform war, and lastly to discuss the mutual constitutive relationship between wars and emotions in the contemporary global durable disorder.
